Overview .. Informatica Repository Stores the metadata created using the Informatica Client tools Tasks in the Informatica Client application such as creating users, analyzing sources, developing mappings or Mapplets, or creating sessions creates metadata Integration Services reads metadata created in the Client application when a session runs Global and local repositories can be created to share metadata Exchange of Metadata with other BI Tools ,Metadata can be Exported to and Imported from BO, Cognos ..The objects exported or Imported can be compared in their XML formats itself. MX Views ,This Feature enables the User to view the Information on the Server Grids and the Object History in the Repository Service . Can be done using the REP_SERVER_NET, REP_SERVER_NET_REF ..tables.

Overview .. Informatica Client Tools Repository Manager To create Repository Users and Groups, assign Privileges and Permissions. Manage Folders and Locks. Print Reports containing Repository Data.

Designer To add source and target definitions to the repository To create mappings that contain data transformation instructions

Workflow Manager & Workflow Monitor To create, schedule, execute and monitor sessions

Repository Manager

Repository Manager Window

Repository The Informatica repository tables have an open architecture

Metadata can include information such as mappings describing how to transform source data sessions indicating when you want the Integration Service to perform the transformations connect strings for sources and targets

The repository also stores administrative information such as usernames and passwords permissions and privileges

There are three different types of repositories: Global repository Local repository

Repository

Can create and store the following types of metadata in the repository: Database connections Global objects Mappings Mapplets Multi-dimensional metadata Reusable transformations Sessions and batches Shortcuts Source definitions Target definitions Transformations

Repository Exchange of Metadata with other BI Tools ,Metadata can be Exported to and Imported from BO, Cognos ..The objects exported or Imported can be compared in their XML formats itself. MX Views ,This Feature enables the User to view the Information on the Server Grids and the Object History in the Repository Service.

Repository Manager Tasks Implement repository security: Create, edit, and delete repository users and user groups Assign and revoke repository privileges and folder permissions View locks and unlock objects

Perform folder functions: Create, edit, and delete folders Copy a folder within the repository or to another repository Compare folders within a repository or in different repositories Add and remove repository reports

Import and export repository connection information in the registry Analyze source/target, mapping, and shortcut dependencies

Repository Security Can plan and implement security using the following features: User groups Repository users Repository privileges Folder permissions Locking

Can assign users to multiple groups Privileges are assigned to groups Can assign privileges to individual usernames and must assign each user to at least one user group

Repository Security Viewing Locks

Can view existing locks in the repository in the Repository Manager

Types of LocksThere are five kinds of locks on repository objects: Read lock - Created when you open a repository object in a folder for which you do not have write permission Write lock - Created when you create or edit a repository object

Execute lock - Created when you start a session or batch Fetch lock - Created when the repository reads information about repository objects from the database Save lock - Created when the repository is being Saved.

Folders Folders provide a way to organize and store all metadata in the repository, including mappings and sessions They are used to store sources, transformations, cubes, dimensions, Mapplets, business components, targets, mappings, sessions and batches Can copy objects from one folder to another Can copy objects across repositories The Designer allows you to create multiple versions within a folder When a new version is created, the Designer creates a copy of all existing mapping metadata in the folder and places it into the new version Can copy a session within a folder, but you cannot copy an individual session to a different folder

Folders To copy all sessions within a folder to a different location, you can copy the entire folder Any mapping in a folder can use only those source and target definitions or reusable transformations that are stored: in the same folder in a shared folder and accessed through a shortcut

The configurable folder properties are: Folder permissions Folder owner Owners group Shared or not shared

Folders Folders have the following permission types: Read permission Write permission Execute permission

Shared folders allow users to create shortcuts to objects in the folder Shortcuts inherit changes to their shared object Once you make a folder shared, you cannot reverse it

Copying Folders

Each time you copy a folder, the Repository Manager copies the following: Sources, transformations, Mapplets, targets, mappings, and business components Sessions and batches Folder versions

Copying Folders

When you copy a folder, the Repository Manager allows to: Re-establish shortcuts Choose an Integration Service Copy connections Copy persisted values Compare folders Replace folders

Comparing Folders The Compare Folders Wizard allows to perform the following comparisons: Compare objects between two folders in the same repository Compare objects between two folders in different repositories Compare objects between two folder versions in the same folder

Each comparison also allows to specify the following comparison criteria: Versions to compare Object types to compare Direction of comparison

Whether or not the Repository Manger notes a similarity or difference between two folders depends on the direction of the comparison

One-way comparisons check the selected objects of Folder1 against the objects in Folder2Two-way comparisons check objects in Folder1 against those in Folder2 and also check objects in Folder2 against those in Folder1

Comparing Folders

Comparing Folders The comparison wizard displays the following usercustomized information: Similarities between objects Differences between objects Outdated objects

Can edit and save the result of the comparison The Repository Manager does not compare the field attributes of the objects in the folders when performing the comparison A two-way comparison can sometimes reveal information a one-way comparison cannot A one-way comparison does not note a difference if an object is present in the target folder but not in the source folder

Folder VersionsAdded Features in PowerCenter 8.1 Can run object queries that return shortcut objects. Can also run object queries based on the latest status of an object. The query can return local objects that are checked out, the latest version of checked in objects, or a collection of all older versions of objects.

Exporting and Importing Objects In the Designer and Workflow Manager, you can export repository objects to an XML file and then import repository objects from the XML file Can export the following repository objects: Sources Targets Transformations Mapplets Mappings Sessions

Can share objects by exporting and importing objects between repositories with the same version

Designer

Screen Shot of Designer

Designer Appendix Informaticas Designer is the client application used to create and manage sources, targets, and the associated mappings between them. The Integration Service uses the instructions configured in the mapping and its associated session to move data from sources to targets. The
